A 46-year-old Costa Mesa woman was killed Sunday night in Rancho Cucamonga after the car she was riding in lost control, the Riverside County Sheriff's Department said in a news release.
The woman, whose name has not been released pending notification of next of kin, was a passenger in a 2005 Mercedes E500 going southbound on Interstate 15 just south of the 210 Freeway when the driver lost control and slammed into the cement shoulder about 11:50 p.m.
Both the driver and passenger were rushed to Arrowhead Regional Medical Center in Colton, where the Costa Mesa woman succumbed to her injuries.
The driver survived, but his or her condition was unknown as of press time.
